I have a big screen tv, about 8 to ten years old. We started to lose the picture, but could restore it by running a fan behind the unit. Lately, the picture will not turn on, even with the fan. Is it worth fixing? We purchased it for very little from a neighbor.

Sounds like your picture tube or bulb is going out. It depends on what kind of tv ( rp, lcd, plasma) it could also be a component issue.

Hmm my dad's old t.v. just cut out on him it took awile to turn on this my be the end of ur tv so this might be a power problem but older t.v. loose there colour on the screen my uncle had a like 10-15 year old t.v the screen was like green when it was light but when u turned of the light or closed the blind's it's picture was ok so try that.

That's a very old model to be only 1 year old?

It needs a Z-Sustain PCB anyway.

Thanks.

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

If the cable was an SVideo, it's possible you might have a broken pin. Losing one of the 4 pins would still give you a picture but it would be in Black and White. Check both ends of the cable and if one is missing, get another SVideo cable.

TRake the fron grill off and the front board 6- screws on my 65inch there are three adjustment knobs one of them wil adjust the huge
one the whole screen,if not that,I have heard mold growing on and the inside of the blue bulb because it runs the coolest out of the three.

try adjusting your color tuners located inside tv behind speakers.

bad voltage regulator - BA09FP requires a bit of tech experience to replace, but its relatively easy. It took me about 1 hour to replace mine. If you need clarification on this, email me at Doin12volt at yahoo

Hi I have the same problem and fixed it by running a fan behind the TV I think the Plasma screen runs to hot.
The fan completely fixed the screen if you feel the top of the TV you can see how hot it gets running a fan behind the set keeps it cool.

So, where are the answers?
